Remit: Appointed as head of the government's rough sleepers unit to reduce the number of rough sleepers by two-thirds. After achieving this target Ms Casey became director of the government's new homelessness directorate.

What she said: Ms Casey caused controversy when she accused homeless charity of scaremongering and creating dependency among rough sleepers through their emphasis on handouts. "You can get a better sleeping bag on the Strand than you can in the camping shop Blacks."

What they said: "We would never try to raise donations by scaremongering," Shaks Ghosh chief executive of housing and homelessness charity Crisis.

What happened next: Ms Casey is about to start a new role to head the government's crusade against antisocial behaviour.
